Overview

The Z Sword looks like a hand-and-a-half sword. Judging by its thin cross-section and wide blade, it appears to be optimized for cutting as opposed to thrusting.

Gohan training to wield the Z Sword

Once every 1,000 years, the Supreme Kais and the Gods of Destruction go to each other's realms and hold a coordination meeting. During one of these meetings, held roughly 75 Million Before Age, they got into an argument over some trifling thing and a certain short-tempered God of Destruction, Beerus, sealedOld Kai away inside the Z Sword as it would not have been proper for him to destroy the Sacred World of the Kais itself.[6] As hard as they tried, none of the Kais that attempted to release the Z Sword were successful.

In Age 774, with Gohan needing medical attention, Supreme Kai brings him to the Sacred World of the Kais to heal as well as to try and release the Z Sword so as to gain access to its legendary power. Despite great difficulty and Kibito constantly decrying him for being a mere mortal, Gohan is successful in freeing the sword upon transforming into a Super Saiyan, stunning Kibito in the process. Though finding difficult to hold the sword due to its weight, Gohan begins training to wield it.

Goku wielding the Z Sword

Later on when Goku visits the Sacred World of the Kais after returning to Other World, he tests Gohan by hurling a large boulder towards him, which the Z Sword cuts through easily. In order to test the sword's limits, Supreme Kai materializes a giant cube made of Katchin, the densest material in the universe, to give Goku to throw at Gohan. Unfortunately, the Z Sword breaks when attempting to slice through the cube. Despite Supreme Kai and Kibito expressing shock and great disappointment over this, not all hope was lost, as the breaking of the blade released the power held within the sword.

Future Trunks training with the Z Sword

In the future, Future Trunks trained with Supreme Kai and Kibito in preparation for Babidi's arrival. Trunks trained with the Z Sword and his power rose to new heights. When Trunks was battling against Future Dabura, Trunks used the sword as his weapon but was later spit on by Dabura, turning it into stone and it broke after Trunks let go of it.[7]

In the game Dragon Ball Z: Shin Budokai - Another Road, Gohan and Supreme Kai go to the Sacred World of the Kais to release the Z Sword only to find that Gohan cannot remove it, resulting in their need of the "chosen one". The "chosen one" turns out to be the Future Gohan, who proceeds to remove the sword easily. The sword can be seen in the game as a projectile attack used by both Gohan and Future Gohan while using Old Kai's Unlock Ability. Ultimate Gohan can also use his Z Sword in several attacks.

In Dragon Ball Z: Battle of Z, the Z Sword appears as a card that can be equipped onto a character. Its positive effects raise the character's melee and ki blast attack power greatly, while its negative effects prevent the character from evading. The Z Sword card is an absolute rare, and appears occasionally in subsequent weekly card releases.

"A replica of a legendary sword from the Kais' world. Gives great power to anyone who draws it."
— Dragon Ball: Xenoverse in-game description

"A long time ago, I was trapped inside a sword known as the Z Sword. It was Lord Beerus who put me in there. Every thousand years, the Supreme Kais and the Gods of Destruction hold a meeting. And we had a teensy disagreement... It all happened so fast... Once I realized what happened, I was already inside of the sword. That was about 75 million years ago, I think... I had nothing but free time. Nothing! I know that Lord Beerus was simply doing what he does, but I want my glorious youth back! Hm? What did we argue about? Hmm... I can't seem to remember."— Elder Kai telling how he was sealed in Xenoverse 2

In Dragon Ball Xenoverse 2, the Z Sword returns as an equipable accessory. After Towa fails to appear in Age 779 after tricking Beerus and Whis by hacking the Time Nest communications and pretending to be Chronoa to lure him and Whis away, Whis suggests sealing Elder Kai as a way for Beerus to vent his anger but Elder Kai protests causing Whis to suggest he spar with Beerus and the Future Warrior. Afterwards as Whis & Beerus are about to leave Elder Kai reveals he still holds a slight grudge over being sealed, though Beerus manages to hear his grumbling and warns him that he can hear him, though decides to not to seal Elder Kai. After Whis and Beerus leave following the sparring session, the Future Warrior can talk to Elder Kai who will tell them how he came to be sealed within the sword. Interestingly, he reveals he had forgotten what the disagreement between him and Beerus was about.
